Resistor (noun)

1. An electrical component that resists the flow of electrical current.
2. A device that opposes the flow of an electric current, used in electronic circuits to regulate voltage or current level.
3. An electronic component that limits or regulates the flow of electrical current in a circuit.

Origin:

The word is derived from the verb "resist" meaning "to oppose or oppose the action of".

Examples:

1. The circuit had a resistor to limit the current.
2. The electronic circuit required a specific value resistor to function properly.
3. The resistor in the circuit was damaged and had to be replaced.
4. The resistor was used to adjust the amount of current flowing in the circuit.
5. The resistor was used to protect the electronic component from high current.
